Twin fin sets are a popular fin configuration in surfing, known for delivering a loose, fast, and playful ride. Typically featuring two fins placed near the rails of the board with no center fin, twin fins excel in small to medium surf where speed and maneuverability are key. This setup allows for smooth, flowing turns and quick down-the-line speed, making them ideal for retro-style fish boards and modern twin fin shapes alike.
Quad rear fins, used in a four-fin (quad) surfboard or setup, provide a unique balance of speed, control, and maneuverability. Positioned closer to the rails and further back on the board, these rear fins work in tandem with the front fins to generate lift and drive, especially in down-the-line surfing.
